Every project we've documented, in one place.

The customer was looking for a proper diagnostic assessment of their property (loft and kitchen) to understand where air leakage and heat loss were actually occurring, before committing to any insulation or draught-proofing works.

On-site Home Health Diagnostic Survey combining a blower door test, smoke testing and a thermal imaging survey.

The thermal images and smoke tests showed exactly where air leakage and heat loss were occurring. George explained the building physics behind each issue so the customer understood the causes, the risks they create and how they relate to each other.

A detailed, well-structured written report was delivered, with clear explanations of the causes, risks and recommended remedial options. The recommendations were honest and practical about priorities, costs and what would (and would not) make a real difference.

The customer received a proper diagnostic assessment — not a superficial inspection. They were extremely impressed with the professionalism and depth of knowledge and would have no hesitation in recommending the service.

A built-in cupboard against an external wall was generating persistent damp and mould — the cold internal surface was sitting below dewpoint on cold days, condensing moisture out of the air and causing the tenant ongoing problems. The property is tenanted, so works needed to be coordinated directly with the tenant around their availability.

Two pre-works site visits to understand the scope properly (no blind phone quoting), combined with FLIR thermal imaging to confirm the cold surfaces and identify the worst-affected areas. The work was then specified as a full internal wall insulation (IWI) build-up using Celotex / Kingspan-equivalent rigid PIR boards — a hygrothermally aware solution sized to bring the internal surface temperature well above dewpoint.

The thermal images confirmed pronounced cold spots and cold bands on the cupboard wall, lintel and reveals — surfaces between 15.7 °C and 17.7 °C against room air of ~21 °C, which is a textbook condensation/mould risk. Two site visits before quoting also revealed the job was trickier than a single day allowed for, so the scope was honestly re-priced to two days rather than rushed.

Full IWI installation to the cold cupboard: rigid PIR insulation boards (Celotex / Kingspan equivalent) fixed to the cold wall, with airtight detailing at junctions to control vapour movement. Access to the tenanted property was arranged directly with the tenant, working around their availability. Project completed under a 1-year workmanship warranty.

A dry, warmer cupboard with the internal surface now well above dewpoint — eliminating the damp and mould source at the root. The tenant is happy with the solution, the landlord has a 1-year warranty, and the job is signed off via the verbatim MyBuilder review.

The customer needed a structured, evidence-based assessment of their whole flat — not a tick-box survey — to understand exactly where heat, comfort and indoor-environment problems were originating, and to receive a fully-costed schedule of recommended improvements they could prioritise and budget against.

On-site Home Health Diagnostic Survey of the flat combining: visual inspection room by room, FLIR thermal imaging of all critical surfaces (walls, ceilings, lintels, reveals, floor junctions, service penetrations), surface temperature and humidity readings, defect identification against building-performance criteria, and conversion of the findings into a costed improvement schedule.

Multiple thermal defects identified and measured across the flat: localised thermal bridges at wall/ceiling corners (cold spots down to 19.1 °C against room baseline ~21 °C), pronounced cold bands along door-head lintels (16.8 °C → 29.4 °C across the same image), a cooler perimeter band at the wall/floor junction (evidence of a heat-loss path through the slab edge), and uniformly cool internal wall surfaces giving an accurate baseline for the costed-improvement comparison.

A thorough written diagnostic report was delivered covering each defect, the building-science reason for it, and a fully-costed schedule of proposed improvements ranked by impact and cost. The recommendations covered thermal-bridge mitigation, perimeter detailing, surface-temperature improvement and a wider Building Performance Strategy the client can implement in stages.

The customer received a proper, evidence-based assessment with full costings for every proposed improvement — exactly what they were looking for. They left a 5-star Checkatrade review describing the report as 'very thorough' with full costings for all proposed improvements, and a glowing recommendation.

The customer needed the existing finished floor lifted so that proper insulation could be installed between the joists — to reduce heat loss into the cold void below and improve airborne and impact noise transmission from the room below.

On-site assessment of the existing suspended-timber floor and the void beneath, followed by a four-stage underfloor build-up: lift existing floor → install mineral wool insulation between joists → fix resilient acoustic bars across the joists → lay new moisture-resistant acoustic boards (RW5 system) as the new deck.

The existing floor build-up offered virtually no thermal or acoustic insulation: heat was being lost downward into the void, and sound was transmitting directly through the joists as both airborne and impact noise. The joists themselves were sound and reusable, so the optimal solution was an insulated, decoupled new deck rather than a full replacement.

Lifted the existing floor and exposed the joists; installed mineral wool insulation between the joists (thermal + acoustic); fixed resilient acoustic bars across the joists to decouple the new deck from the structure; finished with moisture-resistant acoustic boards (RW5 system) ready for the floor finish. Every stage was photographed for the client's records.

A warmer, measurably quieter room with a clean, fully-documented build-up. The client confirmed they would happily reuse RetrofitIQ for similar works or general construction — verified in his Checkatrade review.

The customer was experiencing significant airborne and impact noise transmission through the existing timber floors across multiple rooms — voices, music and footsteps from rooms above and adjacent were clearly audible, affecting day-to-day comfort. One bedroom in particular needed both floor AND wall acoustic upgrades.

On-site assessment of the existing floor and wall build-ups in every affected room, followed by a four-stage acoustic floor upgrade per room (lift existing finishes → mineral wool between joists → resilient acoustic bars → new floorboards → acoustic underlay → new carpet) plus a designed acoustic wall upgrade to the most-affected bedroom.

The existing floors offered no acoustic insulation between joists and no decoupling between the upper finish and the joists. Sound was transmitting directly through the structure as both airborne and impact noise. The most-affected bedroom additionally had a direct flanking path through the party wall requiring an independent acoustic wall layer.

Per room — Stage 1: existing floor finishes removed. Stage 2: RW5 acoustic mineral wool installed between joists. Stage 3: resilient acoustic bars fixed across the joists to decouple the new deck. Stage 4: new floorboards laid, acoustic underlay over, new carpet finished. Additional wall upgrade in one bedroom using independent stud + mineral wool + acoustic plasterboard to break the flanking path.

Measurably quieter rooms across the home with significant reductions in both airborne noise (voices, TV) and impact noise (footsteps). Customer rated the service 10/10 on Checkatrade and confirmed they will be using RetrofitIQ again for further works.
